摘      要：A higher-twist modified parton evolution equation is used to evolve the initial valence quark distributions in pions,which are derived based on light-front quantization via BLFQ *** results are consistent with the valence quark distributions of the E615 experiment,and the pion structure function of the H1 *** structure function data highlight the necessity for a higher-twist modification in the small x *** with some other models are also given.
